django-oscar is a flexible ecommerce platform, designed to build domain-driven ecommerce sites to be constructed. It is not supposed to be a framework that can be downloaded and fully set up by simply adjusting a configuration file: there will always be some developer work required to make sure the models match those from your domain - this is the nature of domain modelling.
However, a small amount of work up front in determine the right models for your shop can really pay off in terms of building a high-quality application that is a pleasure to work with and maintain.
